If you mean you subjected it to a static electricity discharge, whatever damage that did is NOT fixable.
Your mouse is probably damaged - try it in on another computer - if it doesn't work on another computer it IS damaged. If it's a corded USB mouse, wires inside the cord could be broken as well.
Try another USB mouse, in all your USB ports.
If that doesn't help, you may have to disable all the USB controllers in your bios Setup and use a PCI USB 2.0 controller card instead if this is a desktop, or if this is a laptop, use a PCMCIA (PC CARD) USB 2.0 controller card or an ExpressCard USB 2.0 controller card, but, if this is a desktop, you may lose the ability to wake up the computer by moving a USB mouse and a USB keyboard may not work in the bios Setup.
If that doesn't help, you will have to replace the mboard if you want to use USB.
